1.Add the ability to search for images by popularity.
2.Have the blacklist feature actually WORK. It doesn't filter for me.
3.Make racist/offensive subject matter a reason to flag an image. I got a negative vote on my account for flagging a image of a white supremist comicbook cover that some douchebag uploaded. "Isn't that some bs?" thankfully the image in question was deleted by a mod who actually deserves his/her rank before it could cause any drama so kudos to him/her!
